PAINT, AND VABNISH CLEANER.

- My invention relates to cleaning compounds, and more particularly to a cleaning compound for cleaning paint, varnish, enamel, or other surfaces with waterproof coating thereon.

It is a purpose of m invention to ro- ,vide a cleaning powder or paint, varnis or enamel which is adapted to be mixed with water to provide a paste-like mixture which 10 is adapted to be applied with a brush to the surface to be cleaned. After leaving the paste-like coating on the surface to be cleaned for a brief interval of time, the same may be washed off with water by means'of a sponge or'similar member and with the removal of said coating the dirt is removed' from the painted, varnished or enameled surface. The cleaning compound comprises preferably a starchy material, such as corn flour or corn paste, an alkali cleaning agent, such as soda ash, and a gritty substance, such as pumice.

More particularly the. invention comprises a mixture of corn paste or corn flour, soda ash and ground pumice, all of these being in a powdered form-and being thoroughly mixed. 'It' has been found that by using 74% corn paste or corn flour, 17%

. soda ash and 9% ground pumice the best results are obtained. While these proportions 've the best results sli ht variations therefrom may be made-witfiout, seriously affecting the efliciency of the cleaner, but any great variations from the percentages given would produce a compound which will not serve the purpose. The composition referred to above takes u moisture when exposed to the air due to t esoda ash content there of, and in the course of several months the- Application filed February 19', 1928.

sition, the paint would be affected therey, and also if too little soda ash were used, the pro r cleansing action would not take place.

can be applied to the painted surface with a brush and will remain in a moist condition after being placed thereon, so that the same can be readily removed with a wet sponge, after the same has been left on the surface for about two minutes, to remove the dirt therefrom without damaging or removing the paint or other coating material.

In use the dry powder containing the ingredients in t e proportions mentioned above is mixed with water in the proportion of one gallon of water to one pound of the mixture, which makes the paste referred to above. The aste is then applied to the surface to be c eaned with a brush and after having been left on the surface for approximately two minutes the paste-like coating isscribed comprising seventy-four to seventy-- three percent corn flour, sixteen to seventeen percent soda ash and nine percent ground pumice.
